Flux S - Advice regarding ANT+ HR connectivity

Hi all,

I am new to this smart trainer thing and trying to navigate my way through it all.

I am using a Tacx Flux S and here are a few things I have tried so far.....

* Connected Power and Cadence from Flux S directly to Garmin Fenix 5s but watch doesn't detect/calculate any speed or distance so isn't great.

* Used Tacx Flux S with Tacx App on iPhone, seems decent but can't get heart rate up on screen or included in my data so also not perfect.

* Used Tacx Flux S with RGT App on iPhone, had Mac set up with RGT Screen app also with ANT+ USB plugged in hoping that would allow the HR to be detected but also never worked

Basically I want to use one device or app and see all data that then uploads to strava as one file. I understand that I may need to use a bluetooth heart rate monitor but already having ANT+ devices up and running I was hoping that I can get my HR into the action also.

Can anyone help?
